One value of fast frameworks is simplicity. I read once on HN that a lot of modern day deployment strategies and tooling seems like it was created because of very slow apps. When you're running a rails app, you need to scale horizontally, and so you need to orchestrate that, and so you have autoscaling instances, kubernetes, and so on. But if a single, beefy instance can handle all the traffic your app can reasonably expect to see (think, StackOverflow on just a couple instances), then a lot of operational complexity just dissolves away.
